Case: Auto OEM ASRS Real-time Decisions
The flow of painted bodies from the Paint Shop to the
ASRS, and then to TCF can be represented through a
flow diagram indicating the key vertices and arcs.
R30/31: R30/31 is the set of readers on the two lane
buffer at the exit of paint (post polish stage). After painted
bodies cross the R30/R31 readers, there is no divergence
until they reach the next node BT1100. All orders between
R30/31 and BT1100 are the look-ahead available for
RTS.
BT1100: BT1100 is the skid exchange station where the
painted body is transferred from Paint skid to Logistics
skid. At this point, the decision of
storing/bypassing/wax/set out of a painted body is
conveyed to the further PLCs.
PTT01: PTT01 is the turntable at the entrance of the
ASRS. The orders diverge into Lane 1 or Lane 2 of the
ASRS after PTT01.
PTT02: PTT02 is the turntable at the exit of the ASRS.
Orders retrieved from the ASRS converge at this turntable
before being passed to the TCF.
TT02: This is the turntable which routes LTVs to the LTV
TCF buffer. The U202 and W201 bodies continue past
TT02.
TT03: This is the turntable which routes U202s to the
U202 TCF buffer. The W201 bodies continue past TT03.
TT04: Turntable routing W201 to W201 TCF buffer
